Maarten, thanks for the puzzle!
I know difficulties are always a very subjective issue, but I found this one to be rather easy.
I don't want to spoil it for anyone, but no one should be reading feedback for a puzzle not yet finished (or given up on! ).
This one has a single starting place that allowed me to fill the whole grid without doing anything other than straightforwardly avoiding 'connect fours'. Granted, you need to find it.
